I changed my plan of attack from what it was last year. Last year was the "lets kill all the ants and drive them back to the depths of hell from whence they came." Needless to say that didn't work to well, it just quarantined them. This year I've adopted a more friendly attitude. I don't want the ants dead, I just don't want them in my house! They can live outside all the way, just leave my house alone! So I mixed up a spray bottle of: lemon dish soap, borax soap, and water and sprayed huge chunks of my house. Inside and out I sprayed walls and wiped them down with a damp cloth. Reading that site leads me to believe that ants have really sensitive noses so the smellier stuff you can use the better. Since I've sprayed/wiped I haven't seen any ants. So far so good.
